Abstract

AN APPARATUS (100) AND METHOD FOR ENCODING PICTURE DATA. A MOTION VECTOR IS DETECTED AND A DISTRIBUTION RANGE OF THE DETECTED MOTION VECTOR IS DETERMINED. BASED UPON SUCH DISTRIBUTION RANGE, A MOTION VECTOR SEARCH RANGE IS PREDICTED AND SET. DETECTION FOR THE NEXT MOTION VECTOR IS PERFORMED WITHIN THE SET SEARCH RANGE. THE PICTURE DATA AND/OR MOTION VECTORS ARE VARIABLE LENGTH ENCODED, WHEREIN CODES HAVING RELATIVELY SHORT LENGTHS MAY BE UTILIZED. AS A RESULT, THE AMOUNT OF INFORMATION GENERATED DURING SUCH ENCODING MAY BE RELATIVELY SMALL. UPON REPRODUCTION OF SUCH ENCODED DATA, A PICTURE HAVING RELATIVELY HIGH QUALITY MAY BE PRODUCED. (FIG. 1)
